Epimys effectus, sp. u. 



Similar in general colouring to E. ugandce, de Wint., but 

 smaller in size. 



Size and general proportions less than in E. ugandce ; hind 

 foot markedly smaller, measuring only 22 or 23 mm. in 

 length, while in E. ugandce the hind foot is much larger, 

 measuring about 26 or 28 mm. in length. Tail rather short 

 compared with that of E. Uganda. Size of body small. 

 General colour of upper surface brownish buff, the effect 

 being very much as in Apodemus sylvaticus, but rather 

 yellower. Hairs all with slate-grey bases, buff-coloured 

 subterminal rings and dark tips, the dark hair-tips most 

 prominent down the middle of the back. Flanks yellowish 

 buff, faintly speckled with brown, the buffy tint passing 

 abruptly into the white coloration of the ventral surface. 

 Sides of face and neck bright buflf-coloured. Backs of hands 

 and feet white. Entire underparts, as in E. ugandee, greyish 

 white ; hairs of belly all with slate-grey bases and whitish 

 tips. Tail, as in the other members of the multi-mammate 

 gi'oup, almost naked and rather darker above than below. 



Skull markedly smaller than in ugandce, shorter and con- 

 siderably narrower across the zygomatic region. Auditory 

 bull?e and teeth smaller. 



Dimensions of the type (measured in the flesh) : — 



Head and body 139 mm.; tail 124; hind foot 23"5 ; 

 ear 18.
